RALPH G. CARPENTER, OF CHICAGO, ILLINOIS, ASSIGNOR OF ONE-HALF TO HIMSELF AND ONE-HALF TO GEORGE S. BLAKESLEE, OF CHICAGO, ILLINOIS.

CLEANING AND POLISHING- MACHINE.

Specification of Letters Patent.

Patented July 7, 1908.

T 0 all whom it may concern Be it known that I, RALPH G. CARPENTER, a citizen of the United States, residing at Chicago, county of Cook, State of Illinois, have invented certain new and useful Improvements in Cleanin and Polishing Machines, of which the followin is a specification, reference being had to t e accompanyin drawings.

his invention relates to cleaning and polishing machines, and its object is to provide a machine that is adapted to give to a scrubbing brush, or other scrubbing device adapted for cleaning or polishing purposes, a horizontal reciprocating motion of translation whereby a floor or like surface may be cleaned or polished.

A further object is to provide in such machines -a suitable means for suppl ing a cleaning or polishing powder when and where it is needed, and in general to improve such machines in sundry details hereinafter pointed out.

These objects are accom lished by means of the devices shown in t e accompanying drawings and hereinafter specifically described. 4

What I claim to be my invention will be set forth in the claims.

In the drawings :Figure 1 is a side elevation of my device; Fig. 2 is a view showing the other side with one of the wheels removed. Fi 3 is a top or plan view. Fig. 4 is a longitu inal section on line 4 4 of Fig. 7, showing some of the parts in side elevatlon. Fig. 5 is a cross-section on line 5 5 of Fig. 4." Fig. 6 is a cross-section on line 6 6 of Fig. 4. Fi 7 is an enlarged detail,'being a horizontal longitudinal section of the handle of the device, showing some of the arts in top elevation. Fig. 8 is an enlarged detail, being a section through the longitudinal central line of the brush, showing someof the parts in side elevation. Fig. 9 is a section taken at line 9 9 of Fig. 8. Fig. 10 is a bottom view of the brush.

Referring to the drawings :20 is a frame containing an electric motor, from the rear lower corners of which frame do end two arms 21 in which are secured ax es 22 on which are rotatably mounted wheels 23. As is best shown in Fig. 3, from each side of this frame 20 extends a cylindrical stud 24, upon which studs a yoke 25 is sprung, the studs 24 entering corresponding circular openings in theends of the yoke 25. Upon the rear face of this yoke, is a cylindrical stud 26, upon which is secured a hollow handle 27, preferably of metal, as is shown in Figs. 2 and 7.

Throu h a small hollow tube 28 along the side 0? this handle, and through a suitable hole in the rear face of the yoke 25, there pass two insulated wires 29 which are connected with the motor at one end, entering the frame 20 at the point 30, and which, at the other end, are suitably connected with the switch 31 which is secured in the free end of the handle 27. It has not been thou ht necessary to show in detail or to describe t 1s switch, since it may be of any well-known type. It is sufficient to say t at when the Wires 32 leading from the switchare properly connected with any suitable source of electrical energ the circuit between thls source of electrioa energy and the motor can be completed or broken at will by the manipulation of the push buttons 33 and 34, as will be readily understood.

As shown in Figs. 4 and 7, near the free end of the handle 27, there is secured a support 35 which forms a bearing fora slide-rod 36 which is secured at its lower end to a slidable plug 37, of wood or other suitable material. Secured to the upper end of this rod 36 is an arm 38 which extends through a suitable longitudinal slot 39 in the handle 27 as is shown inFig. 1. Upon the outer end of this arm 38 is a thumb-piece 40, by means of which the position in the hollow handle 27 of the slide-rod 36 and plug 37 can be easil regulated. On the under side of the ban le 27 and just above the lowermost position of the plug 37 is an opening 41- leading into a spout 42 which is secured at that point to the handle and which entirely covers the opening 41. As shown, this spout 42 is curved so as to bring its free end to point forward and approximately under the rear edge of the motor. This plug 37 conforms to the shape of the interior of the hollow handle, so that it is evident that when it is in its lowermost position there is a free passage from the interior of the handle, and that when the'plug 37 is drawn up the handle,

through the medium of the rod 36 arm 38 and thumb-piece 40, the plug serves to completely cover the opening 41.

On the upper face of the free end of the handle, just slow the support 35 for the rod 36, thereis an opening 43, the side edges of i which are turned out, as shown in Fig. 5, to hold thereon the cover-plate 44 -which is curved to conform to the shape of the exterior'of the handle and has its edges turned to fit over the turned-out edges of the opening.

It is evident that this cover-plate can be moved longitudinally of the handle so as to cover just so much of the opening 43 as maybe desired. It will be readily understood that a supply of fluid or powdered From the lower part of the front face of the I frame 20 of the motor, projects a lug 46,

forming a socket inwhich is secured a rod 47 which passes through, bearings in the upper ends of two posts 48 and 49 which rise from a plate 50, and which, in the construction shown, are integral therewith, although theymay be otherwise suitably secured thereto. To the plate 50 there is attached, by means of screws 51, a brush 52, through which plate 50 and brush 52 are large central Openings 53 and 54 respectivelv, in which openings pieces of soap may be placed. The

. brush 52 may be otherwise detachably secured to the plate 50 without departingfrom the invention involved. It is of course understood that either the hard soap in the new in the brush itself, and the machine works in exactly the same manner with the other dveices in the place of the brush, it is not thought necessary to show them applied to the machine. It is contemplated to use in this way a sandapering device, a waxing device, or any wel -known device "that may be desired for cleaning or polishing a floor or like surface.

I do not wish to restrict myself to any par 55 ticular shape or size of brush or other cleaning or polishing device. In the drawings the brush is shown as being narrower than the distance between the wheels of the carriage so that the machine as illustrated cannot 0 well be used next to a wall or other obstruction. v Moreover, the brush as shown is rounded at the forward end so that it cannot be used effectively in a corner. Any desired shape of brush for an particular purpose, however, may be use without departing from my invention.

Upon the d'riveshaft 55 of the motor is secured a crank-arm 56, to the outer face of the free end of which is riveted or otherwise pivotally secured an arm 57. This arm 57 is bent inward, as shown in Fig. 3, to bring the front end thereof into contact with an car 58 formed on the upper end'of the upright post 49, with which ear the arm.57 is pivotally connected by means of a screw 59 assing through a suitable opening in the en of the said arm and into a suitable screw-threaded opening in the said ear.

It is plain that if the wires 32 leading from the switch 31 be connected with a suitable source of electrical ener y and the circuit completed by means of the said switch, the

motor will be caused to operate, turning the shaft 55 and crank-arm 56, and, through the medium of the arm 57, causing the plate 50 with its attached cleaning or polishing device to be reciprocated on the rod 47. It is understood, of course, that a long cable may be used between the switch 31 and the point where connection. is made with the line circuit that furnishes the electrical ower, so

that the machine ma be employe to clean or polish a considerab e space without changin the connections.

he motor may be causedto operate very rapidly, thereby securin a very rapid reci rocation of the brush. It is evident that t e scrubbing device will be'more effective if it is of considerable Wei ht than if very light, and I therefore make t e plate 50 of metal, although I do not limit myself to that construction.

What I claim as my invention and desire to secure-'by Letters Patent, is,

1. In a cleaning and polishing machine, the combination with a carriage, a cleaning or polishing device, and means for reciprocatin said device relatively to said carriage, of a ollow handle secured tosaid carriage and adapted to contain and deposit a cleaning or (polishing agent upon the surface being cleane or polished.

2. In a cleaning and polishing machine, the combination with a carriage, a cleaning or polishing device, and means for reciproca'tlng said device relatively to said carriage,

of a hollow handle secured to said carriage, a spout opening out of said handle near its lower end, and'means for regulating the escape of a cleaning or olishing agent from said handle through said spout.
